ApsaraDB for OceanBase:Scale out the storage space

Last Updated:Jan 03, 2023

We recommend that you scale out your storage space when it is running out or when you receive the relevant alerts.


  1. Log on to the ApsaraDB for OceanBase console.

  2. In the left-side navigation pane, click Instances.

  3. On the Instances page, click the name of the target cluster instance to go to the Cluster Instance Workspace page.

  4. Click the More icon in the upper-right corner and select Storage Space Scale-out from the drop-down menu.

  5. In the dialog box that appears, click OK.

  6. Specify the size of storage you want to add and agree to the service agreement.

  7. Click Buy Now and make the payment.


You can scale out the storage space only when all tenants in the cluster are in the Running state. During the storage scale-out, services will be unavailable for several seconds. Therefore, perform this operation during off-peak hours.
